microsoft office 2003 keeps asking for microsoft office 2000 prem.

Hey,

I have office 2003 and when I am in word, some features request that I
insert the office 2000 premium disk to function. When I insert the 2003
disk, it does not work and unfortunately I don't have the 2000 disk. An
example of a function where this occurs is (toolbar)
Format-Theme-Sunflower...when I click on sunflower, it requests the 2000
premium and will not respond to the 2003. Why is this happening and is there
anthing that I can do. I'm quite annoyed but also feel that there must be a
reasonable explanation.
